Dean rolled over in bed, and opened his eyes.

The bathroom light was on, and the shower was running.

He rolled back, looked at the empty bed next to his, and looked at the clock.

4:18 AM.

He rubbed his eyes.

What the hell was Sam doing in the shower at 4:18AM?

Something wasn't right.

Dean walked over to the door and listened.

Through the mask of the shower running was the unmistakable sound of his little brother.

Throwing up.

Dean quietly entered the bathroom room and placed his hand on Sam's shoulder.

He flinched.

"It's ok Sammy, it's ok."
